Example: lr.eval_data

In this example, lr.eval_data returns the byte array from parameter ID into the byte array output_arr.

// Example array of arbitrary bytes.
	byte [] b_arr = new byte[]{(byte)0x12,(byte)0x2,(byte)0x1,(byte)0x3};
// Save the array into parameter ID
	lr.save_data(b_arr,"ID");
// Save the contents of the array parameter to another array
	byte [] output_arr = lr.eval_data("<ID>");
	lr.output_message("This is the value of the first output byte: " 
	    + Byte.toString(output_arr[0]));
